This letter presents a study of the atomic mechanism of the initiation of motion of a static twin plane under applied mechanical load in a model shape-memory material. By tracking the deformation under load and using linear stability analysis, we find that the eigenvalues of the Hessian matrix provide an indicator of the initiation of motion of the twin plane. The initiation of motion is signal...

We have designed and synthesized a new ligand, 6-(2-pyridinyl)-4-[3'-(3-pyridinyl)[1,1'-biphenyl]-3-yl]-2,2'-bipyridine (2). 2 reacted with Pt(cod)(MeCN)(2)(BF(4))(2) to quantitatively give the molecular dimer, 1.BF(4) (2(2).Pt(II)(2).4BF(4)(-)), by self-assembly. The (1)H NMR and UV-vis titration showed that the complexation affinity of 1.BF(4) toward benzenediol guests decreases in the order ...

Thin silicate platelets in a dimension of approximately 80 x 80 x 1 nm(3) are isolated for the first time by a newly developed process involving one-step exfoliation of natural montmorillonite clay and toluene/aqueous NaOH extraction. The platelets are observed to be polygon shape by transmission electron microscopy (TEM) and round bent-leaf shape by dynamic force microscopy (DFM). Individual p...

Abstract Hexagonal boron nitride ( h -BN) has long been recognized as an ideal substrate for electronic devices due to its dangling-bond-free surface, insulating nature and thermal/chemical stability. These properties of the -BN multilayer are mainly determined by lattice structure. Therefore, analyse structure orientation crystals becomes important. Here, stacking order wrinkles investigated t...
